DOORCEECK.

To all whom t may concern.'

Be it known that l, ALBERT SCHMIDT, a citizen of the United States, residinof at Detroit, in the county of Wayne and tate of Michigan, have invented certain new and useful improvements iin Doorchecks, of which the following isaJ specification.

This invention relates to door checks, and especially door checks intended for automobile doors. It has for its object a door check which is completely concealed when the door is closed and which can be made at a minimum cost.

ln the drawings,-

Fig. l is Va cross section through a part of the door and the door post showing the door in dotted lines in its outward position. -f Fig. 2 is a section on the line 2 2 of Fig. 1.

Fig.` 3 is a Flig. 1.

Fig. 4 is a cross section on the.line 1*4 of Fig. 3.

Fig. 5/ is across section on the line 5 5 of Fig. 3.

Fig. 6 is a cross section taken on the line 'section' on .theline 3 3 of eee of Fig. 1.

rl`he concealed door check comprises a post fixture a made up of two plates b and in this o which are spot-welded together. Both these plates are stampings and both are grooved with a horizontal groove d. The Vertical groove 7 is made in the plate b but it does not extend clear to the top and bottom but is simply the length of the head of the "llbolt g. The T-bolt head is placed vertical groove which forms a knuokle.- The groove d is intended to receive the stem of the lbolt when the door 1s swung outwardly, as shown in the dotted lines of Fig. '1.l

lt will be understood that the lbolt is assembled I thehead vof the 'TF-bolt in the loop f or knuckle il and spot-welding the two plates together. rlhis permanently :tastens the rod-like checkmember to the post fixture.

The stile of the door has an obli ue counterbore l, cut in the inside face of (1i-he stile or post. To this secured the door fixture y', simply an escutcheon-like member formed as a stamping. This escutcheon-like member houses a conical rubber washer z' which ltits tightly around the stem of the rlbolt g so that this into the post fixture a .by placingY is adapted to be Application tiled `February 1, 1922.r Serial Nol 533,296.

bolt or checking member cannot `chatter by striking the opening in the escutcheon-like member j.

The end of the T-bolt is threaded as at 7c. Y nut m screws onto the threads on the end of the 'iT-bolt or checking element. This nut together with the rubber washer u is encased in'ya stamped metal shell 0. The washer acts as a lock nut and the complete nut assembly acts as an adjustable abutment to strike the post fixture. The position of this abutment upon t-he stem of the T-bolt regulates the e'e'ctive length of the checkln element.

y locating the post fixture on the inside of the door stile o r post, the entire strength of the stile or post resists the checking action and the fixture is not liable to be torn out of the stile or post by the loosening of the screws. Furthermore, this varrangement completely conceals the fixture on the door.

Further, this check may be used on any door regardless of thickness or width of stiles or doorI posts and regardless of what type of'hinge is attached. rlhe proper adjustment of the doorfor the deslredopening will be made by reaching through the .door-pocket or under the edge of the trimsecured together, a door fixture' through i' which the stem of the lbolt slidably 'e gages, and an abutment on the end of the T-bolt for striking the door xture.

2. lin a door cheek, the combination of a post fixture having a plate provided with a loop-like portion forming a, knuckle and having a horizontal groove leading from the outside of the plate to the said knuckle, a T-bolt having -its head secured in said knuckle and having the stem portion adapt ed to drop into the groove in the lixture when 'the door opens wide, a door fixture through which the stem. o the T slidably engages, and an abutment on the end of the `T-bolt stem for engaging said door xture.

3. lin adoor cheek, the combination with a stile or post having an openmg there'- Mtl -like member through which the rod-likethrough of a post iixtu're, a checking element pivotally secured in said post fixture, and a door fixture securable to the inner face of the stile or post, an abutment on the end of the checking element, `the said checking element passing through the door VIixture and arranged also to pass through said opening in the stile, said abutment arranged to enage a .the door fixture to stop 'the oor in its outward movement.

4. A door eheek, having 1n combination ning therewith a stile provided with an o g element through, a post fixture, va, che

--in the form of a rod-like member pivotally supported in the post fixture, an abutment on the end 'of the rod-like member, and a door fixture in the form of an escutcheonmember slides and which is fastened to the inner face of the stile or post of the door while the rod-like checking member' passes through said opening in the stile or post.

5. A door check, having in combination, a. post fixture, a rod-like checking element pivotally supported in the post fixture, a door fixture through which the rod-like checking element slidably butgloosely en- 1gages, a rubber washer secured in the door xture for en ging the rod-like checking element secure y to preventv chattering. between the checking element and the door tixture, and au abutment on the end of the checking element arranged to engage the doorfixture..

6. A door check, having-in combination, a post fixture com rising a pair of plates,

the front one of W ich '1s provided with a loop-like formation forming a knuckle and both of which are provided with a horizontal roove leadlng from the knuckle to the outside 0f the plates, a T'like bolt having its head securedrin the knuckle when the -two Y plates are fastened together and havingl the stem portion adapted to swing in the orizontal groove when the door swingsoutward1y, anda door fixture through which the' stem of the T- bolt is slidable, andan abutment on the end of the stem-'of the Tv adapted to engage a portion of the door ixture to stop the same.
